Phenol and chlorophenols are long-lived pollutants frequently found in industrial effluents. Phenols are widely used for the commercial production of a wide variety of resins including phenolic resins, epoxy resins and adhesives, and polyamide for various applications. Adsorption process has been proven one of the best water treatment technologies around the world and the removal of diverse types of pollutants from water. However, widespread use of commercial adsorbent is sometimes restricted due to its higher costs. Attempts have been made to develop inexpensive adsorbents utilizing for the reduction of phenol from water. Four types of adsorbent clay, algae, moringa oleifera and rice husk has been used. Among all rice husk shown 97 % of phenol adsorption at 1mm particle size, pH 4, 3 g/l dosing and 150min contact time.

Nigeria has greater challenges when it comes to water development and management. The current water resources development and supply status is unacceptably low and needs a major transformation. With the rapid growth in population, urbanization, industrialization and competition for economic development, water resource has become vulnerable to depletion and degradation. Management of this valuable resource is determined by its acceptability and utilization in terms of quantity and quality. Due to imbalance between demand and availability, management approaches are facing various ethical dilemas. This paper therefore considers the water supply and sanitation situation in the country and the challenges facing the sector. The paper calls for institutional reforms and review of policy targets, define key elements for the development of action and investment plans as well as provide some guidelines in order to minimize duplication and maximize effectiveness. The paper also suggested strategies and viable framework/agenda for sustainable water supply and emphasizes that the machinery of water resources development and management needs an urgent overhauling with the aim of streamlining the overlapping functions of the various agencies that have operated the system up till now. More importantly, the paper suggested integrated approaches/strategies for sustainable management as well as offers relevant policy recommendations for water resources management in Nigeria.

The coliform group has been used extensively as an indicator of water quality and has historically led to the public health protection concept. Total coliforms are a group of bacteria commonly found in the environment, for example in soil or vegetation, as well as the intestines of mammals, including humans. Total coliform bacteria are not likely to cause illness, but their presence indicates that the water supply may be vulnerable to contamination by more harmful microorganisms. Escherichia coli (E. coli) is the only member of the total coliform group of bacteria that is found only in the intestines of mammals, including humans. The presence of E. coli in water indicates recent fecal contamination and may indicate the possible presence of disease-causing pathogens, such as bacteria, viruses, and parasites. Although most strains of E. coli bacteria are harmless, certain strains, such as E.coli 0157:H7, may cause illness. About 80 % of communicable diseases in the world are waterborne. According to WHO estimate about 80 % of water pollution in developing country, like India is carried by domestic waste. In India 70 % of the water is seriously polluted and 75 % of illness and 80 % of the child mortality is attributed to water pollution. The improper management of water systems may cause serious problems in availability and quality of water. The major pathogenic bacteria responsible for water borne disease are spread by the faeco-oral route, in which water may play an intermediate role. The aim of this review is to examine methods currently in use for the detection of coliforms in drinking water and also to evaluate the possible health hazards associated with drinking water contaminated with coliforms.
